The ring seemed to be to the 27-year-old's liking as soon after she responded to his post.

"It's perfect!" she replied.

Whether the whole thing is a joke is yet to be seen, as the engagement has so far been unconfirmed by Diddy's spokesperson. C'mon Dids, you could have at least concocted a series of elaborate Vine videos!

CAUTIOUS ABOUT MARRIAGE

Diddy has had long-term relationships in the past, as well as a high profile relationship with Jennifer Lopez in the late 1990s, but despite having five children, he has never been married.

During an interview on The View last year, the star revealed he had no plans to marry any time soon.

"It definitely would be a dream come true for me to just one day be ready for that [marriage]. I'm not really looking because I know the responsibility that comes with that, and I think that a lot of people, they jump into that and they're not honest with themselves," he said.

"I'm brutally honest with myself. I don't want to get married and not make that woman be the best. I've been close to it, and when I'm ready, I'll make the announcement, but when I do it, I'm doing it forever."
